In one of my projects (WPF, WCF) we are working with server and client side entities. Although the entities look very similar, we had some reasons to separate them: – Client side entities require more logic -> Implementation of INotifyPropertyChanged -> Implementation of IEditableObject -> Restore handling (When user cancels edit) All these functionalities were… Read More »
Data Annotations provide a very nice way to validate the entities. But under some circumstances, you may don’t want to validate all properties. For example, a property like “createddate” we don’t want to validate in the client layer, because the field is not set at this point. In this situation it would be good to… Read More »
I wrote a very tiny MVC Application Framework which runs on OWIN. This Framework uses the Razor engine for the view rendering. It’s very fast because the overhead is quite small. There are just a few lines of code which are between the Owin HTTP server request and the application logic. For that it doesn’t… Read More »
The Razor engine can be used outside of ASP.NET. Beside the cool syntax, it’s a very fast engine! And it’s quite easy to use. In my example I generate a XML file based on a razor template. (You have to install the NuGet package “RazorEngine”. This is my model which I use for the rendering:… Read More »
Microsoft introduced new keywords in C# 5.0 for asynchronous programming. Before C# 5.0 async. programming was only possible with .NET Framework classes. Now it’s implemented in the C# language itself. Here is a simple demo which shows how the keywords can be used. public async Task<string> DownloadFromWeb() { var client = new HttpClient(); return await… Read More »
I created a generator which generates Business and Data Access functionalities based on your domain model. I’ve build this generator + template because I think it makes sense even in smaller web applications to structure the code well. Also when the web application is very simple we never know which requirements we encounter in the… Read More »
The OWIN (Open Web Interface for .NET) specification defines how to decouple web applications from the web server. Detailed information you can get here: http://owin.org Because it’s specification, you won’t find any applications or libraries. One of the concret impelmentations of OWIN is called Katana. Katana is developed by Microsoft and the Community. The code… Read More »
I found the change tracking in WPF always a little bit painful, when working with simple POCOs without any change tracking context (for example ADO.NET EF). Therefore, I wrote a small library which simplifies the tracking. The Lib contains three interesting classes: EditableObject: Imlements the IEditableObject interfaces and handles the revert functionality and change tracking.… Read More »
Most of the websites that we know today, show a similar architecture: – The Client (Browser) request a specific page. – The Server handles the request and returns the result. – The result is displayed on the Browser. – From here the content of the site remains “static”. That means: If the user wants to… Read More »
I’m proudly presenting you my first self-made NuGet package. 🙂 NuGet: ASP.NET MVC Conversational Session (Nuget) GitHub: ASP.NET MVC Conversational Session (GitHub) I’ve created a small extension for ASP.NET MVC which simplifies the session handling in tabbed browsing scenarios. The extension ensures, that your session data won’t be overwritten. For example: Page 1: Contains a… Read More »
